TM 5-3895-374-24-2 Fig.  1-Assembly. NOTE: A    Screw    Conveyor    Drive    consists    of    three    sub- assemblies listed below. 1. Reducer-Includes     speed     reducer,     shaft     retainer, retainer bolt and lockwasher. 2. Adapter Assembly-Includes adapter bolts, lockwashers,  a  lip  type  seal,  2  braided  type  seals  and  seal retaining ring. 3. Drive Shaft-Includes shaft and key. Make  certain  none  of  the  parts  have  been  damaged  in shipment.  Any shipping damage should be promptly reported to   the   carrier.      Read   all   instructions   in   this   manual   before attempting to assemble or install the Screw Conveyor Drive.  It is   important   that   assembly   be   performed   in   the   following sequence and that each step be completed before continuing to the next. ASSEMBLY 1.  Place reducer on blocks that it lays flat with the input shaft down. 2.  Position adapter on reducer output hub so that  small  end (end with 12 holes) rests on  reducer.    Select  the  4  mounting holes  to  match  the  shaft  used  (See  Fig.     1).      Note:      "A" adapters used on SCXT1 and SCXT2 reducers with 1-1/2" drive shafts have only 4 holes on the small end. 3.    Place  adapter  screws  and  lockwashers  thru  adapter  and thread into reducer.  Do Not Tighten. 4.    Select  either  lip  type  or  braided  type  seals  and  install  as follows: Lip  Type  Seals.    Place  seal  in  adapter  so  that  spring  faces out.    Seal  should  be  tapped  evenly  into  place  in  the  adapter with a soft hammer, applying force only on the outer corner of the  seal.    Fill  cavity  between  lips  of  seal  with  grease.    Install seal retainer ring by tapping with a hammer.  Apply grease to adapter    section    of    shaft    (middle    section).        Slide    shaft, keyseated end first, into adopter and thru reducer.  Note:  Be extremely  careful  when  sliding  adapter  section  of  shaft thru   seal   to   prevent   seal   lips   from   being   damaged   or rolled over. Braided type seals.  Flatten both seals with  a  soft  hammer. Place  seals  in  adapter,  one  on  top  of  the  other  with  joints offset  from  each  other.    Lay  retaining  ring  loosely  on  top  of seals.  Slide shaft, keyseated  end  first,  into  adapter  and  thru reducer.  Take care to clear the seals with the adapter section of the shaft.  Once shaft has bottomed, seat retainer ring by simultaneously hitting the face of the ring on opposite sides of the shaft with two hammers. 5.    Carefully  place  reducer  on  its  side.    Rotate  shaft  to align keyseats in shaft and output hub and install key. install shaft retainer, lockwasher and bolt.  Tighten bolt to torque specified in table 3 on page 5. 6.      Lay   reducer   on   blocks   with   input   shaft   down   and tighten  adapter  bolts  to  torque  specified  in  table  3  on page 5. 7.  If waste packing is to be used it may be installed thru access hole provided in the adapter.  Waste packing, not furnished  with  the  Screw  Conveyor  Drive,  may  be  used as  a  separate  seal  option  or  in  combination  with  either the lip or braided seals. INSTALLATION 1.        Determine    the    running    position    of    the    Screw Conveyor Drive.  Running positions are shown in fig.  2. Note that the reducer is supplied with 7 plugs; 5 around the sides of the reducer for horizontal installations and 1 on each face for vertical installations.  These plugs must be arranged relative to the running position as follows: Horizontal  Installations-Install  the  magnetic  drain  plug in the hole closest to the bottom  of  the  reducer.    Throw away   the   tape   that   covers   the   filler/’ventilation   plug   in shipment   and   install   plug   in   topmost   hole.      Of   the   3 remaining  plugs  on  the  sides  of  the  reducer,  the  lowest one is the minimum oil level plug. Vertical  Installations-Install  the  filler/’ventilation  plug  in the hole provided in the top face of the reducer housing. Use  the  hole  in  the  bottom  face  for  the  magnetic  drain plug.      Of   the   5   remaining   holes   on   the   sides   of   the reducer,  use  a  plug  in  the  upper  housing  half  for   the minimum oil level plug.
